Penny: Little finger sandwiches, too. This place is amazing.
Bernadette: Interesting thing about finger sandwiches: you put enough of them together, you got a sandwich.

Bernadette: I had a plan. I kept leaving Dove bar wrappers around to explain any weight gain.
Amy: Where did you get empty Dove bar wrappers?
Bernadette: From all the Dove bars I ate! I'm pregnant! Try to keep up!

Stuart: Oh, so she's good enough for Howard but not for me?
Howard: Yeah.
Bernadette: Yeah. Go have weird relationships with your own mother and cousin. This is his turf.

Leonard: You don't go into science for the money.
Bernadette: Speak for yourself. Last month my company both invented and cured restless eye syndrome. Ka-ching, ya blinky chumps!

Sheldon: Wow! You look beautiful.
Amy: Really? 'Cause I was gonna return it.
Sheldon: Why would you return it? You look like a pile of swans.

Penny: What if you asked for $20 million?
Sheldon: I'm sorry, I'm trying to do science, not hire Lady Gaga to come to my birthday.
Penny: Do you even know who Lady Gaga is?
Sheldon: Presumably, the wife of Lord Gaga.

Sheldon: But I need it. It's the only way to settle the contradictions between gravity and quantum mechanics.
Penny: Well, it's too much money, you can't ask for that all at once.
Sheldon: Well, what if I ask for it in six easy installments of $83,333,333.33?
